Prof Tomas Vetrik, Professor in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), recently delivered his inaugural lecture on the Bloemfontein Campus.

His research area is graph theory, and he mainly focuses on the degree-diameter problem, graph indices, and metric dimension of graphs.

Research focus

According to Prof Vetrik, mathematics was always his favourite subject in school. He also excelled in maths at university and decided to enrol for a course on graph theory while working on his master’s degree. “I liked it, so I also chose topics from graph theory for my PhD thesis,” he says.

In 2014, at the age of 32, he was appointed Associate Professor at the UFS, after postdoctoral research at the University of KwaZulu-Natal and working at the University of Pretoria. An NRF-rated researcher, he has published close to 75 research papers, a third of that as a single author in some of the most well-known journals in his area. Moreover, he was also research supervisor of three PhD and three master’s students.

International collaborations

In the eight years since his appointment at the UFS, Prof Vetrik has made research visits to universities from 14 different countries that have invited him for research collaborations. 

“I am often overseas. I like working from different places. It is interesting to me, and it helps me to be productive,” says Prof Vetrik, explaining some of the inspiration behind his mathematical ideas.

In the next two years, he would like to study more general mathematical problems beyond his current research area.

He says he is addicted to his research. “It overshadows all my other interests.” 

On the rare occasion when he is not working on his research, Prof Vetrik states that he has to keep himself busy. Unable to relax and do nothing, he likes to do sports of some kind or to travel. 

“I am a simple person. I do not even have a TV at home. I use an old-fashioned mobile phone that cannot access the internet,” he says.

South African citizens are yearning for a good story to tell

The 20 Year Review is in essence a continuation of President Jacob Zuma’s State of the Nation Address and the ‘we have a good story to tell’ narrative. The report provides a glowing picture of successes achieved over the two decades. The successes highlighted include the basic human rights enjoyed by South Africans, a marked improvement in economic growth, and the provision of social services such as health care, education and housing. And as expected, the Review is dedicated to Nelson Mandela.

The major accomplishments were made through the strategic policies of the ruling African National Congress (ANC). For example, emphasis has been on improving the lives of South Africans through pro-poor economic interventions, in building social cohesion, investing in economic infrastructure, fighting HIV and AIDS and tuberculosis, which resulted in improved health outcomes.

Generally, the assertions about ‘accomplishments’ have been made against solid evidence and are thus not debatable. What overshadows the 20 Year Review, is the story that is not being told. This is the story of a political economy marred by rampant corruption, high levels of unemployment, declining accountability, and unresponsiveness. This untold story has become the hallmark of President Zuma’s tenure. Meanwhile, the average South African citizen is still yearning for ‘a good story to tell.’
